Q:The total amount of heat released by the fully burnt 200g coke is 60% by mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)], q:(1) how much heat is absorbed by water?(2) if the initial temperature of water is 10 degrees C, then, after absorbing heat, the temperature will rise to how much?

(1) the amount of heat released from complete combustion of coke:Q put =mq=0.2kg * 3 * 107J/kg=6 * 106J.Heat absorbed by water:Q =Q * 106J suction ETA =6 * 60%=3.6 * 106J;(2) Q =cm t suction dreams,Dry water temperatures:Delta t=Q ceilingC water m water=3.6 x 106J4.2 x 103J/ (kg * c) * 10kgC = 85.7,

Q:Purpose of using coke in iron making raw materials

It can capture the oxygen atoms in iron oxide or magnetic iron oxide to form carbon dioxide. The reaction equation is as follows:3C+2 (Fe2O3) = ==3 (CO2) +2Fe at high temperature2C+ (Fe3O4) = ==2 (CO2) +3Fe at high temperature

Q:The two day of the fire is not wang you have a good way to have any good way. Such online

Take the gas stove ignition, and so it was burning 3, and then into the barbecue. Remember to add carbon, open the ventilation cover.

Q:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you

6, the horizontal type coke oven drying machine(7) gas purification circulating water.... supporting technology(8) dry cooling technology of interlayer water-cooled steam.(9) microcomputer precise dosing system

Q:What are the companies that produce coke

Too many enterprises to produce coke. You search on Baidu, coke, a lot of business

Q:Types of coke and use of coke

The vertical furnace processing of low metamorphic coal production of calcium carbide, ferroalloy, coke, chemical fertilizer production and ultra high power electrode, aerospace and medical high technology and high value-added products such as carbon needle coke the world's most complete and unique characteristics of the Chinese coking industrial system.

Q:What's the difference between coke and coke?

Higher than 550 DEG C, semi coke continues to decompose, precipitation of the remaining volatiles (the main component is hydrogen), semi coke weight loss at the same time contraction, the formation of cracks; temperature above the temperature of 800 degrees, the volume of semi coke hardens to form porous coke!

Q:Why is coke used in blast furnace steelmaking?Why not use coal?

(2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.(3) the role of the skeleton: the blast furnace smelting process occurs in the movement and interaction between the rising of the gas and the falling of the charge. The pellets, coke, iron ore, ore and other materials according to a certain proportion, and batch sequence into a blast furnace, blast furnace smelting in reducing atmosphere under the hot metal, after providing to the steelmaking plant of the steel-making.

Q:What are the national standards for grade two coke?

All of these are the main indicators, and the water is not the quality evaluation index. The other is the coke reactivity: no more than 35%; after the reaction intensity: not less than 50%
